## Discrepancy

(CAN) DURING GROUND RUN AFTER ANNUAL INSP OIL APPEARED ON THE WINDSHIELD SHORTLY AFTER STARTING.  ENG WAS SHUTDOWN WITH NO FURTHER DAMAGE AND THE UPPER LT FLANGE OF THE OIL PRESSURE SCREEN HSG WAS FOUND TO BE CRACKED.  UPON REMOVAL OF THE HSG THE FLANGE DEPARTED FROM HSG.  IT DID NOT APPEAR TO HAVE UNDERGONE AN OVER TORQUE, BUT RATHER APPEARED TO HAVE CRACKED/BROKEN DUE TO AGE OR MFG FLAW.
